Trial #5
To evaluate drop-in solvents on second supplied contaminant mix.
Eleven products were selected from the previous test results. Each product was used at full strength in 250 ml beakers at room temperature.
Thirty-three preweighed CDA260 Brass coupons were coated with the second supplied buffing/milling compound mix using a hand held swab. Coupons were allowed to sit overnight and weighed a second time to determine the amount of soil added to each coupon. Three coupons were cleaned in each product for 5 minutes with no agitation. Coupons were air dried at room temperature. Once coupons were dry, final weights were recorded and efficiencies were calculated.
All but one product (Vertrel MCA) removed over 80% of the contaminant within 5 minutes using immersion with no agitation. One product, Metalnox M6960 removed just over 90%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
